Our Genuine AL Series consists of high quality compatible parts at a sizable discount over the original manufacturers cost. All components are brand new and covered under a manufacturers warranty. We take initiative and spot test all new products that arrive to our facility for quality. With the AL series there is no need to worry about getting stuck with the cheap knockoffs you will find plauging Amazon and eBay marketplaces (many of those lamps are DESIGNED to only acheive 30% of the original lamps life!). At Advanced Lamps - Buy smart, buy bright!
